(I'd really like to know. To me, BTC trading and Forex trading sound exactly the same.)
If you're a forex trader, you're trying to make money from people's need to use these currencies.
If you're doing that for crypto, you're doing that but for people who are just also buying and selling crypto - not actual goods or services.
I don't do Forex trading so I'm not particularly defending it. The currency I hold is the one that has utility to me. It's the one I'm paid in, the one I pay taxes in. I don't particularly want it jumping up or down 100s of %. I want it to be stable.
If bitcoin is more stable than your local currency go for it, (although if inflation is 'only' 25% it still doesn't seem to meet that bar). But that says more about your currency than the bitcoin and it still doesn't make it an investment. Your case would seem to be better served by holding USD though.
My first post pointed out it wasn't a very good investment. You seem to be buying it as a store of value, but it isn't very good at that either. So all were left with is a distrust of government. But the cure is worse than the disease.
